When is a good LONG entry for Ethereum?

ETH has come down sharply to the base of the bear channel, even breaking it due to the panic attack that has affected several altcoins, and could be interesting to find an entry with some potential to the top of the channel.

The bearish guideline, and the maximum marked on the chart could show a short-term tendency change. However I don't see Ethereum breaking up the current channel, so this will be only valid for a very quick trade.
